3D Printing On A Much Larger Scale

March 15, 2010 by Mike Szczys 44 Comments

The end goal of this giant rapid prototyping machine is to print buildings. We’re not holding our breath for a brand new Flintstones-esque abode, but their whimsical suggesting of printed buildings on the moon seems like science fiction with potential. The machine operates similar to a RepRap but instead of plastic parts, it prints stone by binding sand with epoxy. This method is not revolutionary, but hasn’t really been seen in applications larger than a square meter or so. It’s fun to see the things we dabble in heading for industrial production applications.

Eat Your Heart Out IPad

March 15, 2010 by Mike Szczys 44 Comments

We don’t remember where we read it, but our favorite criticism of the iPad is that is does the same things a lot of other Apple devices do. So why wait until April to get your hands on that functionality? [Alexbates] built his own iPad clone using existing hardware and software. This started with an MSI wind that he used as a hackintosh. A touchscreen was added to the display, the keyboard removed, and the LCD flipped around. Boom, a tablet running OS X was born. This is different from others because [Alexbates] took the time to alter the UI to look like the iPad. Sure, it doesn’t automatically flip the display when rotated and there’s no pinch-zooming. But it does have more processing power and storage space.

We’re more likely to hack our own like this rather than purchase a device we’re not all that enthusiastic about.

Soil Moisture Sensing

March 15, 2010 by Mike Szczys 31 Comments

These plugs are cheap, easy to make, and work well for measuring the moisture content of soil. The Cheap Vegetable Gardener came up with this method in order to add automatic watering to an automated grow system. Plastic tubing is used as a mold for Plaster of Paris. Once the plaster has been poured, two galvanized nails are inserted. These are won’t rust and work as probes, measuring the resistance of the dried plaster (gypsum). When inserted into the soil, the moisture content within the gypsum will fluctuate along with the soil. As moisture rises, the resistance between the probes falls, which can be monitored by a microcontroller and used to trigger or stop a watering system.

Intense Kit Turns Wacom Tablet Into Cintiq Clone

March 14, 2010 by Mike Szczys 36 Comments

[Lesa Wright] just started selling enclosure kits used to convert a Wacom tabet into a Cintiq clone. You need to start with your own Wacom tablet, there are kits for four different models. You’ll also need to track down some other parts: a compatible laptop LCD screen, controller kit, and some cable extenders. From there, the kit takes over, with several pieces of laser-cut acrylic needing to be glued together properly, then a surprising number of spacers need to be cut from foam board in order to mount everything..

The kits come in at around $225. That might seem a bit steep since you need to bring your own electronics to the party, but have you checked out the price of the original Cintiq? You can expect to drop about twelve-hundred bones on a ready-to-use model. Before you take the dive, you should watch their collection of assembly videos, it’s quite a process.

Flip-top GameCube Portable

March 14, 2010 by Mike Szczys 27 Comments

Here’s another home console made into a portable. [Techknott] built this shiny GameCube handheld. You may remember him from his work on a portable Dreamcast and the wireless Xbox 360 interface. This time around he’s mirrored the finish; a good idea in concept but even his demo images are already plagued by smudges. But if you can keep your digits on the plastic buttons this makes for an eye-catching design. One part that we love is the flip-top screen that hides the optical drive. This is a much better solution than the exposed lens we saw on [Hailrazer’s] GC portable. As always, video after the break.

RFID Reader For IPhone

March 14, 2010 by Mike Szczys 13 Comments

[Benjamin Blundell] built an RFID reader for the iPhone. A jailbroken iPhone connects to this project box by patching into a standard iPhone USB cable. Like in past iPhone serial projects, [Benjamin] is using openFrameworks for the software interface. Right now this reader only detects low-frequency tags but he’s working on the code to read MIFARE tags as well. See the magic of a tag ID displayed on the screen in the video after the break.

Beach Stereo

March 12, 2010 by Mike Szczys 36 Comments

[Adam] wanted a stereo that could stand up to rain and keep sand out. He ended up building this beach stereo out of a cooler. The cooler’s already made to be water tight. He cut holes in the front and back for marine speakers and added a water-tight bezel and cover for the controls on the deck. Inside you’ll find a marine battery to power the unit. Now he and his friends can rock-out even in poor weather thanks to this portable and rugged unit.
